After sentencing, Paula’s 19-year-old daughter, who did not want to be named, said: “My mum was a beautiful, loving and caring person who had a heart of gold. It is impossible to describe the tragedy he has caused our family.

“Although we are pleased with the court verdict, it will never bring back our mum, who we dearly miss.

“We would like to thank all the witnesses who gave evidence at court and the police for their hard work in this case and their support to our family.”

Det Chief Insp John Cox, who led the investigation, said: “The effects of murder are not limited simply to the victim. What is left behind is a trail of devastation in the lives of other people.

“Our sympathies in this case go particularly to Paula’s three children who have been deprived of their mother by this horrific act.”
